VG1 LECP: Voyager 1 Charged Particle Measurements Near Jupiter

Voyager 1's Low Energy Charged Particle experiment data collected in the vicinity of Jupiter. The dataset includes 48.0-second rate and flux measurements for electrons and ions across almost 100 instrument channels, with particles including protons, alpha particles, and light to heavy nuclei. NASA produced this globally calibrated dataset, last updated on the platform in April 2026.

Use Cases

• Modeling Jupiter's magnetospheric dynamics based on in-situ charged particle intensities.
• Analyzing energy spectra of ions and electrons based on the >30 keV and >15 keV energy ranges.
• Studying the composition of particle populations near Jupiter based on species discrimination for protons, alpha particles, and nuclei.
• Investigating temporal variations in particle flux based on 48.0-second step measurements synchronized with instrument rotation.

Strengths

• Data is globally calibrated to the extent possible, as stated in the description.
• Includes measurements from almost 100 distinct Low Energy Charged Particle instrument channels.
• Provides 48.0-second temporal resolution for flux and rate data during the Jupiter far encounter.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment for specific modeling tasks.
• Description metadata is limited; actual data quality requires manual inspection after download.
